BOTTLE-STOPPER.

SPECIFICATION forming part of Letters Patent No. 561,191, dated June 2,1896.

' Application filed July 2, 1895. Serial No. 554,717. (No model.)

.To all whom it may concern.-

Be it known thatweJ-IARVEY P. BARNHART and SAMUEL L. BARNHART, citizensof the United States, residing at Potsdam, in the county of St. Lawrenceand State of New York, have invented a new and useful Improvement inBottle-Stoppers, of which the following is a specification.

This invention relates to bottle-stopper fas- Io teners which consist,essentially, of a swinging bail pivoted to the neck of the bottle and aclamping device carried by the bail and adapted to bear upon the cap orcover of the bottle, our present improvement being esper 5 ciallyadvantageous in connection with milkbottles which are closed by aseparate cap or disk. Such a bottle is shown and described in LettersPatent of the United States No.

411,368, granted to us September 17 1889.

The object of our invention is the provision of a fastening of this kindwhereby the cap can be readily secured and released and which can beproduced at small cost.

In the accompanying drawings, Figure 1 is z 5 a fragmentary verticalsection of a milk-bottle provided with our improved fastener. Fig. 2 isa view at right angles to Fig. 1, showing the position of the partspreparatory to clamping the cap or disk. Fig. 3 is a detached 3operspective view of the bail and cam. Fig. 4 is a sectional elevationshowing a modified construction of the cam. Fig. 5 is a vertical sectionthereof at right angles to Fig. 4L.

Like letters of reference refer to like parts 3 5 in the several gures.

A represents the neck of the bottle, provided in its upper end with ashallow annular recess a, and YB is a cap or cover closing the mouth ofthe bottle and seated in said re- 4o cess, whereby the cap is heldagainst lateral displacement. This cap preferably consists of a thindisk of wood or paper-board, such as is described in the Letters Patenthereinbefore referred to.

O is the swinging bail or yoke having its side members provided withinwardly-extending pivots which are preferably journaled in sockets orindentations formed in the neck of the bottle, as shown in the drawings.

5o D is 'the clamping-cam carried by the bail and adapted to bear uponthe cap of the bottle for confining the same in its seat. This camconsists of a swinging loop depending from the cross-bar of the bail andbearing with its lower horizontal portion upon the cap. The loop issplit or divided on its upper side, and its end portions are bent upwardat right angles to the body of the loop to form attachin g-lips whichlatter are provided with openings through which the cross-bar of thebail passes loosely. In order to confine the lips upon the middle of thebail, the central portion of the latter is offset, as shown, to formstop-shoulders c. The curved end portions of the loop render the sameelastic, and the lips thereof are separated by an intervening spacewhich permits the same to move toward or from each other in locking andreleasing the loop, whereby the elasticity of the loop is increased. Theloop is preferably bent from a comparatively wide strip of sheet metalto afford the requisite bearing-surface upon the cap.

In securing the cap or disk the bail is swung into its upright position,and the cam-loop is at the same time swung under the cross-bar of thebail, t-he flat lower portion of the loop bearing squarely upon the capwhen both the bail and the loop stand in an upright position, as shownin Fig. 1,thereby firmly clamping the cap upon its seat. To release thecap, the bail is simply pressed laterally, whereby the cam-loop is swungout of line with the bail and unlocked, permitting the removal of thecap.

In the modiiication of our invention shown in Figs. 4L and 5 the ends ofthe cam-loop are rigidly connected by an upright swivel-bolt f, which ispivoted to the offset portion of the bail by an eye f. The lower portionof this bolt passes loosely through openings formed in the overlappingends of the cam-loop, and its lower end is headed for retaining the loopon the bolt. This swiveling connection permits the cam-loop to be turnedat right angles to the bail,if desired, as shown,whereby the fastener isrendered more secure.

While We prefer to employ a thin disk-like cap of wood or paper-boardfor closing the bottle, it is obvious that our improved fastening mayalso beused with a glass or metallic cover.

IOO

Ve claim as our invention- .l. The combination with a bottle or similarvessel and a cover, of a swinging bail pivoted to the upper portion ofthe bottle and adapted to extend over the oever, and a clamping-Cainconsisting of an open elastie loop pivotally suspended from said bailand having a flat and eomparatively wide lower side which bears upon theoever of the bottle, the upper side of the loop being substantiallyparallel with its lower side and the end portions which eenneet itsupper and lower sides being curved, whereby the iiat lower side isrendered yielding substantially as set forth.

2. The Combination with a bottle or other vessel and a oever, of aswinging bail pivoted to the upper portion of the bottle and adapted toextend over the cover, and a split cani-loop pivotally suspended fromthe swinging bail and having a continuous unbroken lower side whichbears upon the cover of the vessel and having,` its end portionsarranged on the upper side of the loop and bent upwardly at an angle tothe upper side of the loop and perforated to receive the cross-bar ofthe bail, said perforated end portions being separated by a space whichpermits the saine to nieve toward and from each other, as the cani-loopexpands and contracts in looking and releasin g it, substantially as setforth.

lVitness our hands this 17th day oi' June,
